Specification of Letters Patent.

' Patented Jan. 28, 1908.

Application filed January 2| 1907- Serial No. 3504Z4u To all whom it mayconcern:

Be it known that I, DAVID B. Lnwrs, a citizen of the United States, anda resident of Bisbee, in the county of Cochise and Territory of Arizona,have invented certain new and useful Improvements in Miners Shovels, ofwhich the following is a specification.

This invention relates to hand shovels and more especially to squareminers shovels.

The object of the invention is to provide an improved shovel blade fortaking up rock and ore which will slip easily thereunder and scoop it upclean.

In the accompanying drawings, Figure 1 represents a perspective view ofa shovel blade embodying this invention; Fig. 2 represents alongitudinal section thereof; Fig. 3 represents a top plan view of theblade; Fig. 4 represents a bottom plan view of the blade.

In the embodiment illustrated, a square blade 1 is shown, the upper orrear end of which is of the ordinary construction, being bent upwardlyand having an upstruck apertured portion 2 to receive the handle 3. Theside edges 4 and 5 of the blade are curved upwardly at the rear endthereof and in clined gradually downwardly and outwardly from the reartoward the front and merge into the flat front end near the middle ofthe l blade about three inches, more or less, from the edge of saidfront end. These side edges are parallel with each other and lie in thesame plane, and the front portion of the blade being fiat across theentire width thereof presents no obstructions to the coal or ore to beelevated, and permits the blade to slip readily thereunder with theleast possible resistance. By this construction the inner faces of theside edges are arranged in approximately a horizontal plane.

I claim as my invention 1 A square shovel blade composed of a singlethin sheet of metal having its front portion flat and straight acrossits entire width with the sides thereof curved upwardly at the rear endof the blade and bent outwardly and downwardly toward the front, merginginto said flat front portion near the middle of the blade and with theirinner faces lying in approximately a horizontal plane, said sheet havingits rear end bent upwardly from a point beyond the middle, whereby acentral depression is formed to receive the material to be lifted.
